Preparing for Operation

3.1 Special safety instructions

• The mower is designed solely for agricultural use (operation in accordance with specifications)

• While working with the mower, all ersonnel must keep a sufficient safety distance from the cutting tools.

• The support skids must be on the ground before the machine is switched on and during operation.

• Even when the mower is used in accordance with specifications, stones etc. may be thrown out.

Therefore, nobody must be allowed to enter the danger area. Special care must be taken when working near roads and buildings.

• The protective cloth covers must be checked regularly. Worn and damaged cloth covers must be replaced.

3.2 Attaching the Disc Mower to the

Tractor

3.2.1 Hitch points

• There are two locations for hitching the mower to the tractor.

The lower link pins are of cat. II + cat. III.Normally the mower is attached to the tractor in position 1 (cat.II).

For wider tractors or when working in combination with a front-mounted mower (of abt. 2.8 to 3.2 m working width), the mower should be attached to position 2.

1

POS.1

X

In addition the lower hitch pins (1) can be installed in position 1 or 2 for a lateral offset of X = 50 mm.

X

• The protective features on the mower, e.g. cloth covers and guard plates, are designed to protect from stones etc. that are thrown out and to prevent access to dangerous parts of the machine.

Therefore it is essential that they are in position before work commences.

• When the mower is moved from transport position to mowing position or back to transport position, nobody must be allowed to go between the tractor and the mower.

• Special care is required when fitting implements to the tractor or removing them. It is essential that the accident prevention regulations are observed.

Preparing for Operation

3.2.2 Coupling

• Secure the lower links (1) to the hitch points provided for this.

• Attach top link (2) to the top hole of the 3-pt headstock.

2

The lower link arms on the tractor must be fixed with the limiting chains or rods to prevent the machine swinging out during transport or operation.

1

If the lower links (1) are equipped with quick release hitches, the following points must be observed:

• In particular in headland position, high forces occur in the lower linkage bolts

(3), which act upwards in the left-hand side hitch.

This is why the hitches must be in very good condition.

• Additionally, after coupling, the hitches must be secured against accidental opening using the locking holes (4) provided.

3.2.3 Axle load

The permissible values for total weight, axle and tyre load must not be exceeded as a result of machines being hitched to the front and rear 3-pt linkage of the tractor. If a rearmounted machine is installed, the load on the tractor front axle must never be inferior to 20% of the tractor’s dead weight.

Be sure that these requirements are fulfilled before moving on.

The PTO shaft must only be fitted and removed when the PTO shaft and engine are switched off and the ignition key has been removed.Secure the tractor against rolling away.

Be sure that the locking device of the PTO shaft locks into engagement.

Secure the guard tubes to prevent them rotating with the shaft.

3.3.1 Adapting the PTO shaft

• Hold the PTO shaft halves (1) and (2) next to each other

• Check the overlap of the attachment and protective tubes

• Shorten profile and shielding tubes so that in its shortest operating position the PTO shaft can be pushed together by at least 150 mm. (This clearance is required to be able to push the PTO shaft together if the spring-loaded breakaway device is actuated).

• Adapting the length of the shaft is described in detail in the PTO shaft manufacturer's operating instructions

Check the swivel space and the free movement space for the PTO shaft. If the PTO shaft touches the tractor or the attachment, this can cause damage.

• Push the PTO shaft (1) onto the tractor PTO shaft and secure

• Secure the protective tube using the retaining chain

(2) so it does not rotate with the shaft

3.4 PTO shaft for the conditioner drive

• The PTO shaft for the conditioner drive is mounted with the friction clutch (1) towards the gearbox and the free-running end (2) towards the conditioner.

Attach the retaining chain (3) to the mower.

3.5.1 Special safety instructions

• When connecting the hydraulic hoses to the tractor, the hydraulic system on both sides must be free from pressure!

• When tracing leakages, use suitable aids and wear protective goggles to prevent injury.

• Fluid escaping under high pressure

(hydraulic oil) can penetrate the skin and cause serious injury! If such injuries occur, consult a doctor immediately. Danger of infection!

3.5.2 Connecting the hydraulic hose

A single control valve is required on the tractor to operate the disc mower. The hydraulic hose (3) is coupled into the coupling sleeve (1) of the control valve. The operating rope (2) used to control the lifting procedure into „transport position“ should be fixed at a convenient point on the tractor.

When the hydraulic hose is connected, the hydraulic control device must be in floating position or in the “Lower” position.

• The control cable must be so positioned that it can not cause any accidental movements in any transport or working positions

• The control cable does not come into contact with the tractor tyres.

3.5.3 Jack Stand

With disc mower in operating position, jack stand (2) must be raised and secured by pin (1).

Make sure that the jack stand is in the raised position before switching on the mower.

4.1 Special safety instructions

Adjustments must always be made only when the drive is switched off and the tractor engine is at a standstill! Remove the ignition key! Secure the tractor against rolling away.

4.1.1 Adjusting the cutting height

Cutting height can be varied by adjusting top link (1).

This adjustment should be performed with the mower in parking position:

• Release the compensating springs

• Lower the mower onto the prop stand.

Longer top link arm = longer cutting height

Shorter top link arm = shorter cutting height

4.2 djusting the guards

Lateral guards

The lateral guards are adjustable for height.

For this release the bolts (1) and (2) and move carrier arm (3) to the desired height. Retighten the bolts.

Front guards

The position of the front guards depends on the height adjustment of the lateral guards.

Dimension a = 440 mm. Choose the position

of the guards that matches the height of the crop to be mown. Adjusting front guard (1) to dimension “a” ensures the best possible protection against objects being thrown away.

The guard is then parallel to the ground.

• The adjustment of the compensation springs must only be carried out when the disc mower is in transport position. In working position, the compensation springs are under a high tension.

• Taking off the compensation springs

4.3 Adjusting the compensation springs

The ground pressure of the cutter bar will be adjusted to the local conditions via the three compensation springs.

In order to protect the turf, the cutter bar has to be relieved of the load so much that it doesn’t jump while mowing and at the same time, that it doesn’t leave any tracks on the ground.

Move the mower to transport position to adjust the compensating springs. Only in this position it is possible and permissible to change the bolted position of the lever which is used to adjust the tension of the compensating springs.

4.4 Adjusting the breakaway unit

To protect the disc mower from damage caused by impact with obstacles, the mower is fitted with a springloaded breakaway unit.

The correct setting for the moment of actuation is preset in the factory.

Mower - Type Distance x

EASYCUT 280 CV 75 mm

EASYCUT 320 CV 75 mm

EC-099-1

Any modification to the setting will also change the torque of the breakaway system. If the tension of the spring is increased beyond the value prescribed by the manufacturer, there is a risk of damage to the disc mower.

The setting of the spring of the safety breakaway must ensure that the system is not released in the transport position in case of sudden loads.

Once the safety breakaway is released, the mowing unit swings back and at the same time its front part moves to the top. That allows small obstacles such as stones to be driven over. Reversing the tractor will cause the safety breakaway to be reset in the initial position.
